Hi,
Measure the difference in the offset of the new fork/yokes compared with the origonals,
This is the measurment between the center of the steering stem and the center of the fork leg.
If the replacements have a smaller measurment then the trail will be increased and this will slow the steering and make the bike stable at high speeds, If this is less be very carful the bike may turn in very fast and become unstable at hight speeds, and be prone to tank slappers. ( the wider front tyre will also make it turn in quicker......
look at this

and do the math.

They may look good but the benafits are very small , spend the money on having the Honda forks re valved and sprung, and invest in a good rear shock and the very best tyres you can get.
If you want sharper turn in increase the rear ride hight and drop the forks through the yokes 10mm.



Hope this helps.

Dave.
